Hi, How can you access the <root> of the Linux system? I'm struggling with this as the code above results in an invalid handle, as it cannot access '/'.</root> I am using Control for Raspberry Pi for context. Thanks.

Hi, please share your codesys ide version and the version of the communication addon. Do you use encrypted communication? Did the browsing in the ide work? Did you create the certificate for the client in the security screen? BR

Hi, Recently, I purchased a license for PubSub communication from the CODESYS store. Unfortunately, after installation, I couldn't find any example code in the files. Is there anyone who can share such an example/send links or help with writing such communication in ST language?"

Any way I can read the value of the 'request counter' (see screenshot) in my application. Amount of client connections is easily found using ModbusTCP_Slave_Device.uiClientConnections; But for request counter it does not seem to be that simple.

Post by jonathan1321351 on IO-Link write parameters Ethernet/IP ^{CODESYS Forge talk (Post)}
I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Post by john-martin on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
Hi everybody, I am looking for a solution to send files, for example, to an ftp or a cloud. I can't use oscat library because 64 bit controller are not supported. Therefore, I see that the IIoT library has some functions that might help me to implement this sending process in codesys. Does anyone have any examples of how to do this? I have spent some days with this issue without success. Best regards.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

Post by tyronnosaurus on ReceiveWatchdog FB not working on J1939 P2P PGNs ^{CODESYS Forge talk (Post)}
Hi guys. I've got a device that sends a status message over J1939 and a PLC running Codesys to receive it. This message uses a P2P PGN (as opposed to a broadcast PGN). Codesys can only read it if I mark the J1939_ECU as "Local" (see screenshot 1). The message is received correctly, that is not the problem. The problem is detecting if the message stops being received. Local ECUs have no Watchdog checkbox to detect if the message has been received in the last X seconds. In order to implement a watchdog, I've used a ReceiveWatchdog FB. The same code works well for any non-P2P message, but doesn't work for this particular P2P message I'm trying to monitor. Even if I physically disconnect the device, ReceiveWatchdog.xBusy stays True, and ReceiveWatchdog.xError never triggers due to a timeout error. Is there any caveat in the ReceiveWatchdog FB that makes it unable to monitor P2P PGNs in Local J1939_ECUs?

Post by testlogic on Sending Sequential Modbus TCP Packets ^{CODESYS Forge talk (Post)}
I have a Modbus TCP slave device where I need to do sequential writes to the same register. The register I'm writing to is kind of like a command line, each packet is a command word encoded in Hexadecimal. I am having difficulty implementing this system in CoDeSys 3.5 SP19. I feel like the structure of the program should be something along the lines of (Pseudocode): ModbusTCPSend(Command Register, Command1) ModbusTCPSend(Command Register, Command2) ModbusTCPSend(Command Register, Command3) I have tried to implement this with a rising edge trigger wMot1OPCode := 16#E1; //Stop Motor & Kill Program xMot1SendOP := TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset wMot1OPCode := 16#9E; //Disable Motor xMot1SendOP :=TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset Where "wMot1OPCode" is the IO map for writing to the command register, and "xMot1SendOP" is the rising edge trigger for that modbus channel. However, this doesn't work. The device never responds to the modbus commands. It seems like the trigger variable is switched too quickly for modbus to send the packet. I know the modbus register is working, because I can set the channel to cyclic and the device will respond. However, I can't use this reliably because I need each command to be sent once, in order. Cyclic keeps re-sending the commands and seems like it could miss a command as well if one was sent in-between cycle time. I have also trying using the Application trigger as described by https://faq.codesys.com/pages/viewpage.action?pageId=24510480, but this is also not working for me. See attached picture for my FBD code. This seems like a simple function, I can't tell what I'm doing wrong here. Thanks for the help.
